Waterproof casing

Waterproof casing structure is divided into the form of a flexible waterproof casing (A / B tube), rigid waterproof casing (A / B / C type) and three types of rigid waterproof wing ring. Flexible waterproof casing applied to seismic fortification areas, through the wall of the pipe to withstand vibration and pipeline stretching deformation, or have strict water requirements of structure (building) buildings facades. Rigid waterproof casing pipe through the wall at a suitable pipe is not subjected to vibration and stretching deformation of the structure (building) buildings for seismic fortification requirements, such as the use of rigid waterproof casing, should enter the wall or walls on the building Official Road nearby to set a flexible connection. Also known as waterproof casing wall bushing, wall pipe. Flexible waterproof casing pipe through the wall are generally applicable to the Department by vibration or water tight structures required, after the sleeve portion of processing is completed, both in its outer wall paint brush again (including primer Zhang Dan or cold base oil) . Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. Both places are mainly used in different, flexible waterproof casing is mainly used in air defense high wall, pool and other requirements of local, rigid waterproof casing pipe is generally used in basements and other places need to wear pipeline location. Either rigid or flexible waterproof casing is waterproof casing for pipeline through by vibration or water tight walls of buildings required hardware accessories, commonly used in construction, chemical, steel, water, sewage treatment and other units.
